Fig. 4From: Constrained incremental tree building: new absolute fast converging phylogeny estimation methods with improved scalability and accuracyHow constrained INC uses constraint trees to insert taxa. Left: the induced tree topology on taxon set \(\{a,b,d,f\}\) of t in Fig. 3. Right: the subtree of t (on leaf set \(\{v,q,e,f\}\) corresponding to the edge vf from the left subfigureBack to article page
